How is speed calculated? What is the difference between average and instantaneous speed?
Understand the Problem
The question appears to be asking about the concept of speed and how to calculate it, including average speed and instantaneous speed. It also provides examples and illustrations to aid understanding.
Answer
Speed is distance divided by time. Average speed is total distance over total time; instantaneous speed is at a specific moment.
To calculate speed, divide the distance traveled by the time taken. Average speed is the total distance divided by total time, whereas instantaneous speed is the speed at a specific moment.
Answer for screen readers
To calculate speed, divide the distance traveled by the time taken. Average speed is the total distance divided by total time, whereas instantaneous speed is the speed at a specific moment.
More Information
Speed can be measured in meters per second (m/s) or kilometers per hour (km/h). The concept is essential in understanding motion.
Tips
Mistakes often occur by confusing distance or displacement for calculating speed. Ensure units are consistent when performing calculations.
